Abstract (en)
[origin: WO8001906A1] An ozone generator (11) is formed by a plurality of concentric tubular plate members (13a)-(11d) supporting positive and negative electrodes (14a)-(14d) which are interleaved with each other. A high voltage discharge is applied from a transformer (17) between the electrodes (14a)-(14d) to cause an electric discharge in the air contained therebetween, thereby generating a supply of ozone. The air is fed to a suction nozzle device (15) through which a water stream (41) to be purified passes. The suction nozzle (15) is constructed so that the water stream (41) is markedly speeded up so as to generate a partial vacuum in an air pocket (42) formed between the water stream and the inner walls of the nozzle. The ozone, which is fed to the nozzle (15) in the region where this air pocket (42) is formed, is thus sucked into the nozzle (15) and efficiently injected into the water stream (41), thereby effecting the purifying action.

Un generateur d'ozone (11) est forme par une pluralite de plaques tubulaires concentriques (13a-13d) supportant des electrodes positives et negatives (14a-14d) qui sont intercalees entre elles. Une decharge a haute tension est appliquee a partir d'un transformateur (17) entre les electrodes (14a-14b) pour provoquer une decharge electrique dans l'air contenu entre elles, permettant ainsi de produire de l'ozone. L'air est envoye a un dispositif d'ajutage d'aspiration (15) a travers lequel passe un courant d'eau (41) a purifier. L'ajutage d'aspiration (15) est construit de maniere telle que le courant d'eau (41) soit considerablement accelere de maniere a engendrer un vide partiel dans la poche d'air (42) formee entre le courant d'eau et les parois internes de l'ajutage. L'ozone, qui est envoyee a l'ajutage (15) dans la region ou cette poche d'air (42) est formee, est aspiree dans l'ajutage (15) et injectee efficacement dans le courant d'eau (41), exercant ainsi l'action de purification.
